Riku Rei summons Suigin after her father, Riku Yuuki dies, and hands him something that Yuuki apparently left for him. Though he is hesitant, Suigin accepts the item, which happens to be a specialized console to play the new game “Grave Buster.” On the console, Riku Yuuki left Suigin a message and one billion in inheritance and tells him to protect Riku Rei.
Though I'm certain you don't remember me.
لكن أنا متأكّد أنّك لا تتذكّرني
Auch wenn ich mir sicher bin,
dass du dich nicht an mich erinnerst.
Aunque seguro que no me recuerdas.
Aunque seguro que no me recuerdas.
Mais je doute
que tu t’en souviennes.
Anche se sono certo
 che non ti ricordi di me.
Apesar de que tenho certeza 
que não se recorda de mim.
Хотя я уверен, что ты меня не помнишь.
